LiftMaster 877LM Wireless Keyless Entry Keypad 5-Pack
The LiftMaster 877LM 5-Pack is a bulk package of Security+ 2.0 wireless keyless entry keypads for compatible yellow learn button garage door opener systems. This set is designed for customers, technicians, and property managers who need several matching keypads for multiple openers, multiple doors, or service replacement inventory. Each keypad allows exterior garage access with a personal 4-digit PIN, reducing the need to carry a handheld remote when entering through the garage.
The 877LM is part of the LiftMaster Security+ 2.0 accessory family. It is commonly used with LiftMaster, Chamberlain, Sears Craftsman, and Raynor residential garage door openers that use the yellow learn button platform. This keypad should not be treated as a direct fit for older green, red/orange, or purple learn button systems. On those older systems, a different keypad or universal keypad may be required.
What This Keypad Does
The keypad sends a wireless access command to a compatible opener after the correct PIN is entered. It is mounted outside the garage, typically near the door jamb, and is commonly used for family entry, service access, tenant access, and secondary access where a remote control is not convenient. The keypad does not replace the wall control inside the garage and does not add smartphone control by itself.

The LiftMaster 877LM is commonly associated with Security+ 2.0 yellow learn button garage door opener systems. Compatibility depends on the opener radio technology and learn button color.

Technician Note
When replacing multiple keypads, program and test one keypad first before programming the rest of the pack. If the first keypad will not program, confirm the opener learn button color, the antenna condition, and whether the opener is actually Security+ 2.0. Weak range can also be caused by electrical noise, LED bulb interference, a damaged opener antenna, or a keypad battery issue.
Before Ordering, Confirm
- The opener has a yellow learn button
- The system uses Security+ 2.0 radio technology
- The customer needs a keypad, not a wall control or handheld remote
- The quantity needed matches the pack size
- The existing keypad is not for an older green, red/orange, or purple learn button opener
Professional Advisory
After programming, test keypad operation from outside the garage while the door is in full view. Do not use a keypad to operate a door with damaged hardware, missing safety sensors, or unsafe movement. If the opener does not respond correctly after programming, inspect the opener, photo eyes, wiring, and door balance before assuming the keypad is defective.
Important Ordering Warnings
- This is a Security+ 2.0 keypad pack, not a universal keypad pack
- Do not select 877LM for older non-yellow learn button systems without confirming compatibility
- If the customer needs compatibility across several learn button colors, review 877MAX or another universal keypad option
- Pack quantity should be confirmed before publishing or upload
Questions & Answers
What opener systems use the LiftMaster 877LM keypad?
The 877LM is used with compatible LiftMaster, Chamberlain, Craftsman, Sears, and Raynor Security+ 2.0 garage door openers that have a yellow learn button.
Is this 877LM keypad pack universal?
No. The 877LM is not a universal keypad for all LiftMaster openers. It is intended for Security+ 2.0 yellow learn button systems, while older green, red/orange, and purple learn button openers use different keypad options.
Why buy the 877LM as a 5-pack?
The 5-pack is useful when several doors or locations need matching wireless keypads, such as multi-door homes, small facilities, rental properties, or service inventory.
Can each keypad use a different PIN?
Yes. Each keypad is programmed separately, so each keypad can be assigned its own PIN and paired to the compatible opener it will control.
What should be checked before replacing an old keypad with 877LM?
Check the opener learn button color, opener model, radio technology, and whether the existing system is Security+ 2.0. The 877LM should not be selected only by keypad appearance.
